Abstract

In this work, a library of 3D lumped components completely embedded in the thinnest, multilayer liquid crystal polymer (M-LCP) stack-up with four metallization layers and 100m of total thickness, is reported for the flrst time. A vertically and horizontally interdigitated capacitor, realized in this stack-up, provides higher self resonant frequency as compared to a similarly sized conventional parallel plate capacitor. Based on the above mentioned library, a miniaturized bandpass fllter is presented for the GPS application. It utilizes mutually coupled inductors and is the smallest reported in the literature with a size of (0:035 £ 0:028 £ 0:00089)‚g. The M-LCP module presented in this work is inherently ∞exible and ofiers great potential for wearable and conformal applications.
